T400 undervolting:
todo: https://wiki.archlinux.org/index.php/PHC

* get PHC
  * time yaourt -S phc-intel
* find safe voltages
  * get mprime first
    \ $ time yaourt -S mprime
  * read?
    \ https://bbs.archlinux.org/viewtopic.php?pid=1141702#p1141702
  * wget https://bitbucket.org/stqn/shell-tools/raw/master/mprime-phc-setup
  * chmod +x mprime-phc-setup
  * load PHC module, somehow
    - reboot - no effect
    * FIXME: must make dkms build it! (package says it should/would, but doesn't!)
  * sync
  * # time ./mprime-phc-setup
    \ as root

might need Windows:
- get Orthos to test if stable! (Go - ORTHOS BETA by Johnny Lee)
"The really nice thing about using ORTHOS to stress test your cpu is that you really don't need to worry that much about getting a BSOD because ORTHOS will detect a hardware failure and halt the test."

- get rmclock or a least cpu usage one: ThrottleStop
(see the comment above the one pointed by "src:" ^ above)
//- also see:
//"You guys might be interested in trying NHC, notebook hardware control. It allows for voltages as low as 0.7v. One thing though: it doesn't support as many notebooks as RMClock, so your lappy might not be supported. I used to run .7v on a 1.86Ghz Sonoma @ 800Mhz."

NHC can only do 32 bit! ignore it!

yeah I can't undervolt this under Windows! the programs seem to be reporting
unreliable/variable voltages (vids/fids) such as rmclock...
so, temporarily gave up on this, maybe I'll try under linux
